摘　　要：通过对不同橡塑比的EPDM/TPX进行动态硫化研究,发现当共混比60/40时,共混物的综合性能较好。在不同的温度下对橡塑比为60/40的共混物进行动态硫化,研究发现在230℃下动态硫化的效果较好。另外,对橡塑比为60/40的EPDM/TPX在不同转速下进行研究,结果表明当转速为70 r/min时,共混物的力学性能较好。Through the dynamic vulcanization research on various rubber plastic ratios of EPDM / TPX, we found that the blend had better overall performance when the blending ratio was 60/40. At different temperatures, we dynamically vulcanized the 60/40 blend, and found that the dynamic vulcanization effect was better at 230℃. In addition, we studied the 60/40 EPDM / TPX at different speeds, and the results showed that the blend has better mechanical properties when the speed was 70 r / min.
